CornerRibbon is the indicator form of kamo-login's sign-in pane ribbon: a thin shaded diagonal band across an item's top-left corner, in any colour, at three sizes. It clips itself to its own corner box and inherits the parent's radius, so a parent only needs position: relative. It replaces the rail on the bug card, the drawer's status-reason callout, the thread's quoted parent and its replying-to bar, and the SI handoff card shown in the thread (shared with Live Support).
